COBNER-CHAMFERING MACHINE FOR MATRICES.

Application filed January 16, 1907.

To all whom it may concern:

Be it known that I, I-Ionaon A. REYNOLDS, residing at IVoonsocket, in the county of Providence and State of Rhode Island, have invented a certain new and useful Improvement in Corner-Ohamfering Machines for Matrices, of which the following is a full, clear, and exact description.

The matrices which are used in linotyping machines are small blocks of brass having a -depression in one edge in which is an intaglio character depression. In order that these matrices may move freely through a linotyping machine, and may, when assembled in line, have no interstices between them, it is necessary that their edges be very smooth and entirely free from burs or other slight projections. This result may be quickly secured by very slightly beveling all of the corners of a matrix, excepting only the corners formed at the junction of the sides and that vertical edge in which the character depression is formed.

This invent-ion is a machine with which to accurately and quickly bevel the two vertical corners at the rear edge of the matrix, the two vertical corners formed by the vertical channel in said matrix, and the two corners along the top edge and the two corners along the bottom edge of a matrix. And the invention consists of the construction and combinations of parts embodied in said ma chine shown in the drawings and as hereinafter described and definitely pointed out in the claims.

In the drawings, Figure 1 is a plan view of a machine embodying the invention. Fig. 2 is a front elevation thereof. Fig. 3 is a seetional front elevation in the plane indicated by line 3-3 of Fig. 1. Fig. l is a sectional end view on the plane indicated by line H on Fig. 1. Fig. 5 is a plan view of that part of the bed plate in which the channels a, a are formed, and a sectional view of certain knives by which the upper corners of the matrices are beveled. Fig. 6 is a fragmentary sectional view in the plane indicated by line 6-6 on Fig. 5. Fig. 7 is a fragmentary sectional view in the plane indicated by line 7-7 of Fig. 5. And Fig. 8 is a perspective view of such a matrix as this machine is designed to operate upon, showing it in the condition in which it preferably is as to completeness when operated upon in the machine shown.

Serial No. 352,623.

Referring to the drawings, A represents the bed plate of the machine, a portion of which is, as shown in Figs. 3 and 4:, raised above the level of the rest of said bed plate. In this raised portion are two channels a and a, which intersect each other at right angles, the bottom of said two channels being in the same horizontal plane. The width of channel a is substantially equal to the width of a matrix, and the width of channel (1 is substantially equal to the height of a matrix.

B is a feed magazine which is secured over the channel a, so that the bottom of said channel shall serve as the bottom of the magazine. A slide G- is provided by means of which the bottom matrix of a pile of matrices in said magazine may be pushed out and toward the other channel a. The lower end of this magazine should be in such position that the slide G and the lowest matrix in the pile and no other may be moved in said channel under said lower edge.

On that side of the magazine under which a matrix is pushed by slide G is a vertically movable guided presser foot F which is pressed downward into the channel a by means of a spring f A lever f which is pivoted to the magazine B enters a notch f in the side of the stem of this presser foot, whereby the presser foot may be raised so as to permit a matrix to pass beneath it. The other magazine D is for the purpose of receiving the matrices after they have been beveled in the machine. It is secured above the channel a so that the matrix being pushed along the channel a may pass under it.

A vertically movable presser foot. 0 has its stem 0 mounted in a vertical guide way in a fixed standard N,the spring 0 being provided for pressing it downward. A. lever Q pivoted to the same standard enters a slot in the stem 0 and thereby affords means by which this presser foot may be raised. The presser foot extends over the inter-see tion of the-two channels a, a and additionally extends a short distance over each of said channels toward the respective magazines.

A slide J is movable in the channel a; and the power for moving it as well as the slide G is furnished by a cam groove .9 in rotatable shaft S. The slide G carries a pin 9 on which is a friction roller g and this pin and roller enter the cam groove. A,

slide J mounted in suitable guide ways is also provided with a pin carrying a friction roller 7' which also enters the same cam groove. A. bell crank lever U is pivoted to the under side of the bed plate. One arm is connected by a link a with the slide J; and the other arm is connected by a link a with a block j secured to slide J. The two slides G and J, therefore, operate reciprocally. Referring, particularly, to Fig. 1, it will be noted that when slide pushes the bottom matrix out of the magazine B, the slide J is being moved toward the front of the machine. When the machine is in operation matrices are being pus-nod out of the magazine B along the channel a, and there will always be a. row of four of said matrices in said channel, including the bottom matrix of the pile in magazine B, as well as the head matrix of the row which is also in the channel a. Vi hen the slide G- 'is ret acted after having moved this line of matrices into the position described the slide J moves rearward and pushes the said end matrix rearward toward the magazine D. In the construction shown there will be a row of four of these matrices in the channel a. The presser feet F and U will. be holding most of these matrices down in the channel. llhen a matrix is brought under the magazine D it plate, and one arm of this lever engaged by a cam s secured to shaft S, by means of which the plunger is periodically raised. The matrices as they are raised by the plunger pass the spring fingers X, engaging with their beveled lower surfaces and pushing them outward; but said spring fingers fly below the lowest matrix when it sufficiently elevated, and thereafter sustain it and all of the matrices above it.

As the matrices pass along in the channel a, they pass under three scraping or beveling knives E. These knives are fitted in vertical grooves in a vertically movable block 1 This block is moved up and down by means of a screw V passing through a flange 72 therein, and having shoulders engaging with the upper and lower surfaces of said flange; and this screw screws into a threaded hole in the top of a fixed standard Z. Each of the knives has upon its upper end a small finger c which engages in an annular groove 6 in a screw 0 which screws down into said block P. The entire block may' be moved up and down to adapt the machine for work upon matrices of different thicknesses, by turning the screw V; and the knives may be also separately adjusted by turning the several screws 6. These knives are so placed and shaped that one of them engages with one of the vertical corners of the matrix and the other two engage with the vertical corners of the channel at which is formed in one side of the matrix iii. Passing up through suitable grooves in the bed plate of the machine another knife E which is directly below that knife E which engages with one of the vertical corners of the matrix; and this knife E engages with the lower corner of the matrix and bevels it. The lower end of this knife has a finger c engaging in an annular groove in a screw which screws into the under side of bed plate A. There is another vertial block R-having a vertical tongue and groove connection with a fixed standard K. This block has a flange '1 through which passes the shank of a screw L which screws into said standard K, and this screw shank has shoulders which engage respectively with the upper and lower surfaces of said flange r, and thereby this block may be vertically adjusted required. This block carries two knives E adapted to engage with the corners of a matrix, at the top and bottom thereof, when the matrix is being pushed along in the groove a. These knives have fingers c at their upper end which respectively engage with annular grooves in screws c screwing down into said block. Two other knives E" passing up through holes in the bed plate engage with the other end corners of said matrices, being below the two knives E respectively. These lower knives e have fingers which engage in annular grooves in screws a which screw into the lower side of the bed plate. VVheu, therefore, the row of matrices is being pushed along channel a, the knives E IE will scrape oti' the sharp corners along the rear edge of the matrix and along the longitudinal channel m, and as said matrices are pushed along channel a, the sharp corners of the top and bottom of the matrices will be scraped off by the knives E E The presser feet F and 0 will hold the matrices down in these grooves, and a part of one matrix at least will be under each presser foot, holding it up as another matrix is pushed under it.

Having described my invention, I claim:

1. In a machine for beveling the corners of matrices, the combination of a bed plate having in its top surface two connected channels which are at right angles to each other and whose bottoms are in the same horizontal plane, a feed magazine secured over one of said channels, a push bar movable in said channel beneath said magazine, another push bar movable in the other channel, two parallel slides, means for imparting reciprocal motion to said slides, and mechanism connecting said slides respectively to said two push bars.
